OneDrive Duplicate File Finder

This tool connects to your personal Microsoft OneDrive
or OneDrive for Business account and looks for files
that are duplicates. Two files are considered duplicate
when they have the same SHA-1 hash (for personal
accounts) or the same
QuickXorHash
(for OneDrive for Business accounts).

During the scan, the page reloads repeatedly.
